"I used to want to be a rapper when I was, like, 14," Robert confessed to Oprah with a laugh, when asked about how he learned to speak with an American accent.

"No you didn't!" a stunned Oprah said.

The British heartthrob also said a love of cinema from this side of the pond helped.

"I grew up watching American movies and stuff," the actor, who turns 24, on Thursday told Oprah.

When Oprah turned to Taylor, she asked what millions of fans are dying to know – what the 18-year-old star wants in a girlfriend.

"Obviously, loyalty," Taylor – who has been reportedly linked to Taylor Swift and Selena Gomez – told the talk show host. "Really important to me is somebody who can totally let loose and pretty much be themselves and have fun."
